U.S. airlines are estimated to be sitting on more than $10 billion in travel vouchers that should have been cash refunds from canceled flights, a group of senators released on Friday.
Many U.S. airlines are canceling between 60 percent and 80 percent of their flights, and under federal law passengers on those flights are entitled to full refunds, Senators Ed Markey, Elizabeth Warren, and Richard Blumenthal said in a statement.
